PORTLAND, Maine (AP) — Authorities say a 74-year-old Maine man will appear in court this week to face charges in the shooting deaths of two of his tenants inside their apartment after a possible dispute over where they parked their cars during a snowstorm.

James Pak was arrested Saturday night after a standoff at his home in Biddeford. He is charged with two counts of murder in the deaths of 19-year-old Derrick Thompson and Thompson's girlfriend, 18-year-old Alivia Welch.

Thompson's mother called police around 7 p.m. to report the shootings. She suffered a gunshot wound but her 6-year-old son was not injured. Both live in the apartment.

State police spokesman Steve McCausland says Biddeford police were called to Pak's home earlier over a dispute about cars being parked in the driveway during the snowstorm.
